Ntawm cov kab ntau lawm ntawm Ningbo Guangway Machinery, Tus Thawj Coj General Mr. Chen tau khaws cov khoom siv lub tshuab tshiab tshiab. "Peb cov khoom pib nrog forging," nws hais. Txhua yam khoom pib nrog kev ua tib zoo forged dawb paug, kom ntseeg tau tias muaj cov qauv sab hauv thiab txhim khu kev qha.
Tom qab ntawd, cov blanks nkag mus rau hauv CNC machining theem, qhov uas lawv tau ua tiav rau hauv cov khoom tiav lawm siv precision CNC tshuab cuab yeej. Mr. Chen tau hais tias, "Qhov tseeb yog lub neej ntawm cov li qub; tsis muaj chaw rau qhov yuam kev ntawm no."
Cov kauj ruam tseem ceeb tshaj plaws yog kev kho saum npoo. Txhua qhov chaw yog thawj phosphated, tsim ib zaj duab xis tiv thaiv ntawm cov hlau nto los txhim kho adhesion; Tom qab ntawd, electrostatic hmoov txheej yog siv, thiab tom qab siab -kub curing, muaj zog, corrosion- tiv taus txheej yog tsim.
"Phosphating raws li lub hauv paus tsho tiv no, ua raws li cov hmoov txheej - cov txheej txheem 'ob chav tiv thaiv' ua rau kom lub neej ntev ntawm cov li qub nyob rau hauv ib puag ncig hnyav," Mr. Chen xaus lus. Cov txheej txheem paub tab no yog qhov tseeb vim li cas Guangway Machinery lub valve Cheebtsam tau txais kev ntseeg siab hauv kev xav tau kev lag luam.
